In /etc/postfix/main.cf I am supposed to add:
owner_request_special = no
because:
By default, Postfix treats -owner and -request addresses
specially. Since we want Postfix to deliver such messages to
Mailman, you should turn off this option by adding this to your
main.cf file:
owner_request_special = no
What kind of problems could I get if I do not add that line? I removed it,
and I am not aware of any problems.
